A new acetophenone diglycoside, 2,4-dihydroxy-6-methoxy-3-methyl-acetophenone 4-O-gentiobioside (1), along with six know analogues (2–6), were isolated from the roots of Euphorbia ebracteolata. The structures of these isolates were determined by UV, HRESIMS, 1D and 2D NMR spectral analyses. In addition, all acetophenones showed moderate DPPH free radical scavenging capability, and no cytotoxicity against
一种新的苯乙酮二糖苷,2,4-二羟基-6-甲氧基-3-甲基-苯乙酮-4- Ö -gentiobioside(1),具有六个知类似物(沿2 - 6),从根分离月腺大戟。这些分离物的结构通过紫外,HRESIMS,1D和2D NMR光谱分析确定。此外,所有的苯乙酮均显示中等的DPPH自由基清除能力,并且对五种人类癌细胞系均无细胞毒性。
